It solves the problems of poor stability and poor clamping effect of existing centrifugal casting machines. The workpiece clamping device of the centrifugal casting machine includes a base, a fixed seat arranged on the base, and a movable seat that can move horizontally. A first turntable is arranged on the fixed seat, and the central axis of the first turntable extends along the moving direction of the movable seat. A second turntable is arranged on the movable seat. The first turntable and the second turntable are coaxial and oppositely arranged. A traction unit for making the movable seat approach or move away from the fixed seat is arranged between the fixed seat and the movable seat. There are two traction units and they are symmetrically arranged along the central axis of the first turntable. The utility model has the advantages of good stability and good clamping effect.

[0003] The existing workpiece clamping device is not convenient for replacing the chuck. After long-term use, the chuck will be damaged and the chuck needs to be replaced. Generally, the chuck is fixed and installed by bolts. When disassembling and assembling, tools are needed to disassemble and assemble it. The operation is cumbersome, which increases the workload and reduces the work efficiency. It is also not convenient for assembling and disassembling workpieces. Generally, the workpiece is fixed by rotating the screw to move the screw and drive the pressure wheel to press the workpiece. This fixing method requires repeated rotation of the screw when disassembling and assembling the workpiece. The operation is cumbersome, which increases the workload and reduces the efficiency of assembly and disassembly. It is not convenient to use. In order to solve the above-mentioned problems, we propose a workpiece clamping device for a centrifugal casting machine. Utility Model Content
